CrateGroupInfo cannot provide CcInfo dependencies for experimental_cc_common_link

If you use a rust_library_group or rust_prost_library with a rust_binary using experimental_cc_common_link, the resulting link likely fails because the code for collecting the linking contexts for deps doesn't search any crate_group_info instances. rust_prost_library in particular always returns a CrateGroupInfo for its output, linking against it always fails.
